GUY W. FERDON, OF CRESSKILL, NEW JERSEY.

GQLLAPSIBLE s'rovn.

Specification of Letters latent.

Application filed July 13, 1916. Serial No. 109,068.

Be it known that I, GUY citizen of the United States, residing atCresskill, county of- Bergen, State of New Jersey, have invented certainnew and 'useful Improvements in Collapsible Stoves; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to collapsible stoves or heaters, and particularlyrelates to a deviceadapted to be used for cooking with alcohol lamps,whether the lamps be those which use solid or liquid alcohol; though thedevice is not restricted to the use of this particular fuel, but burnersor lamps supplied with other solid, liquid, or gaseous fuel may beemployed in connection with my device.

My invention particularly relates to a folding stove of the kind thatcan be folded into a small package and carried about in an automobilekit, by hand, or as an article of luggage, which may be instantly set upand used for picnic or other cooking.

In the drawing: Figure 1 is a side view of my device; Fig. 2 is aperspective view looking upward from beneath, showing the device set upand ready for use; Fig. 3 is a bottom view showing the device partly setup and partly in folded position; and Fig. 4: is a perspective view ofmy lamp supporting and frame bracing shelf or support.

My stove consists of a hot plate 1, formed of thin sheet metal. Forstrengthening and.

- rigidity, this sheet metal plate is bent or turned around thestiffening wire 2, except at the corners, whereby the plate is keptstill. In the top of this plate I'provide grate openings 3, and grates4, of a common type. These grates are bolted intoplace by the bolts andnuts The grate openings and grates maybe omitted, if desired, or othergrates of different form may be substituted. The number may vary. To theunder part ofsaid hot plate I secure, at each end, a pair of eyelets 6;about midway of said plates, on each side, I provide a pair of clips 7,secured in place by bolts 8. I form supporting legs one for each end ofsaid plate, out of a single piece of wire,

W. FERooN, a

bent as shown in Fig. 2 and Fig. 3; that is,

the upper part of each leg is provided with two horlzontal portionsforming pintles 9, whlch engage the eyelets 6. Extending from thesepintles, and at practically right angles thereto, are the long reaches10, and at right angles to these are the feet 11. Extending verticallyfrom these feet 11 and, as shown,

practically in the plane of the rest of the legs or supports, are theshort reaches 12. Connecting these short reaches, at their upper ends,is, for each pair of legs, a single horizontal reach 13, for a purposeto be referred to later.

It will be seen that each pair of legs, or each support, is pivoted uponthe plate and adapted to swing in such pivots. To brace such legs andsupport them rigidly, I provide two means. One of these is a pair ofbrackets 14:, each one of a single piece of wire, and hinged at the topand bottom of each respective long reach 10. This hing ing iseli ectedby bending the ends of the bracket into rings or eyelets, as shown. Thegeneral contour of the bracket, as shown in Fig. 2, consists of a.forward horizontal reach extending from the upper end of the leg reach,and the diagonal reach extending from the lower end of the leg reach.Each of these brackets may be swung into position beneath one of theclips 7, as shown in Figs. 2 and 3, and is thus held pinched against theunder side of the plate .th suflicient rigidity to keep the legs stiff.

hen the legs are folded down against the plate these brackets are swungin behind the legs and rest against them. In order to be able to make aneat and compact folding, the length of each bracket should not be muchmore than the width of each pair of legs. It will be noted thattheeyelets at the end of each bracket are so bent that the bracket, whenswung backward, will rest neatly and compactly against its support. Theupper reach of the bracket may be in contact with the plate. It isprovided with an oilset to enable it to clear theeyelet 6, as

I shown.

also of a piece of sheet metal, the edges of which are turned u toimpart rigidity. The end of each shel is turned downward, as shown inFig. 2,-part of the way, so that the turned down end forms a loop 16, asshown in F igl 4. These loops are of the same length a proximately, asthe length of the horizonta reaches 13, and fit snugly over saidreaches, so that when these loops are placed in position the plateextends between the two reaches and aids in su porting and givingstiffness to the whole evice.

When the stoveis knocked down, or reduced to folded condition, the shelf15 is, of course, removed and laid alongside the parts folded together.When the stove is set up, the shelf 15 affords a support for any of thealcohol burners or lamps of the usual market type, or for the solidalcohol cans, such as are in common use, the distance between the shelfand the hot plate and grate openings being such as to suit the use ofsuch lamps .or fuel.

I have illustrated by outline, two solid alcohol cans in position on theshelf. It will be observed that the stove Ls adapted to use-any ofthese, whether large or small. Moreover, the position of the lamps neednot necessarily be under the grate openings. The entire shelf may beheated, if desired, and, as intimated previously, the grate holes may beomitted. 4

In setting up the device the legs are first bent to the position shownin ig. 2, the brackets turned and laced under the clips 7, and the shelf15 placed in position. All this is the work of but a moment, and thestove is ready for the rece tion of the alcohol burner, which is p acedon the shelf 15. 4

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States, is:

1. In a support for heaters, in combination, a hot plate, legs hinged tothe under side of said plate and adapted to be folded against saidplate, means adapted to fold against said legs for keeping said legs inopen position, and means when the device is in use, for supportingheating devices in proper relation to said hot plate.

2. In a stand for supporting heaters, in combination, a hot plate, legshinged to the ends of said plate and adapted to fold inward against theunder side of said plate, brackets hinged to said legs and adapted to befolded when said legs are folded and to be opened to supporting positionwhen said legs are unfolded to supporting position, and clips with whichsaid brackets are adapted to engage.

3. In a stand for supporting heaters, in combination. a hot plate. legshinged thereo and adapted to be folded against the plate, bracketsattached to said legs and adapted to be folded upon the legs, and

clips on the under side of the plate with which said brackets engagewhen the legs and brackets are unfolded.

4; In a support for holding heating devices, in combination, a sheetmetal hot plate, eyes secured to the under side of said plate at theends, bent wire legs, mounted pivotally in said eyes, bent wire bracketspivoted upon the legs and adapted to fold backward upon said legs, andwire clips upon the under side of said plate and adapted to hold saidbrackets in position to hold the legs rigid when unfolded.
